The device forming the subject matter of this application is adapted tobe used for attening out dents in many places on an automobile, es-

Y pecially dents in the fenders.

One object of the invention is to provide a simple indicating meanswhereby the operator may know exactly where the hammer is going tostrike, relatively to the dent, even though the hammer cannot be seen. Afurther object of the invention is to supply novel means for mountingand controlling the indicator, a further object of the invention beingto improve the construction o f the dent-removing. hammer and to improvethe mounting thereof. i

Stated in shorter Words, by placing the indicator pin of the devicedirectly over a low spot, an operator can then raise the low spot to itsproper level, forreinishing the metal with a body file, sanding disk orthe like, and do so without any guess work. v It is withinthe provinceof the disclosure to improve generally and to enhance the utility ofdevices of that type to which the present invention appertains.

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thesco'pe of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings:

Fig. 1 shows in elevation, a tool constructed in accordance with theinvention, one of the guides being in section;

Fig. 2 is a section on the line 2-2 of Fig. 1;

Fig. 3 is a sectional view, showing in detail, the indicator and itsmounting;

Fig. 4 is an elevation disclosing a modification in the hammer;

Fig. 5 is an elevation showing a modied form of the invention. t

Referring to the form depicted in Figs. 1, 2 and 3, the tool is shown ascomprising a substantially U-shaped frame 3, which, in the interest oflightness combined with strength, may be made of tubular stock. Theframe 3 comprises a first arm I and a second arm 2, arranged inapproximate parallelism, the arms being joined together,

in an integral structure, by an intermediate por tion 4.

The free end of the rst arm I carries, rigidly,

right angles to that arm. An annular stop 6 is fixed in the first guide5, as Fig. 3 shows. guide plug 'I is threaded into the outer end of thefirst tubular guide 5, and is supplied at its inner Aend with a centralbore 8.

An indicator pin 9 is mounted for straight line reciprocation in thestop'G and in the bore 8 of the guide plug 'I. The indicator pin 9 has apointed inner end I0. An annular labutment IIv is secured to theindicator pin 9, within the guide 5. The abutment II is'adapted to makecontact with-the stop 6, and when the parts are in engagement, the outerend of the indicator pin 9 still is in the bore 8 of Vthe guide plug 1.A compression spring I2 surrounds a portion of the indicator pin 9, oneend of the spring finding abutment against the inner end of the plug 1,and the opposite end of the spring engaging the abutment II.

A second tubular guide I4 is secured to the free end of the second arm 2and is disposed approximately at right angles thereto. arranged incoaxial relation with respect to the guide 5. The guide I4 is suppliedwith enlarged end portions I5, receiving bushings I6.

A hammer rod Il is guided for straight line movement in the bushings I6and in the intermediate portion of the guide I4. At its inner end, ahammer rod II is provided with a bluntly pointed nose I8, located inaxial alinement with the pointed end I0 vof the indicator pin 9. Inorder to prevent the hammer rod I'I from rotating, it carries a lateralprojection I9, such as a machine screw, received and guided in alongitudinal slot 2D in the guide I4.

The hammer rod Il may be operated in various ways. It can be actuated bythe hand of an operator, to impart a light, medium or heavy blow,raising the low spots their proper level. If desired, a handle (not sown) may be mounted on the outer end of the hammer rod Il, the hammerrod being provided with a disk.2I, serving as a stop or abutment for thehandle.

In the event that the hammer rod I1 wears away the bushings I6 and thevintermediate portion of the guide I4, to such an extent that the hammerrod does not travel in true coaxialrelation with respect to theindicator pin 9, this difficulty can be remedied by removing wornbushings I6 and substituting new bushings. y

The tool is straddled on the fender or other piece of material uponwhich the work is to be done. The pointed indicator pin 9, advanced bythe spring I 2, can be seen readily, and its pointed a first tubularguide 5, disposed approximately at end III may be placed accurately withregard to The guide I4 is the dent that is to be raised. The operator'then knows that the hammer rod I1 will raise the dent, when the hammerrod is reciprocated. AThe indicator pin 9 retires, compressing thespring I2, and the hammer rod I1 does its work, raising the dentaccordingly.

The pointed end I8 of the hammer rod II is useful for raising a smalldent only, but the working end of the hammer rod may be of any desiredshape. In Fig. 4, parts hereinbefore de.; scribed have been designatedby numerals already used,-with the suiiix a. In that view, the hamplace,the hammer being disposed alwaysv in a' position for use. l

Having thus described the invention, what is claimed is:

1. In a dent-removing tool, a substantially U- shaped frame includingfirst and second arms, a first tubular guide secured intermediate itsends to the free end of the rst arm, a second tubular guide securedintermediate its ends to the free end of the second arm, bushingsremovably mounted in the ends of the second guide, a hammer mounted forreciprocation in the bushings, and a spring-pressed indicator movablymounted in the rst guide, independently ofthe bushings, the innerrendsor the indicator end of the hammer being disposed in axial alinement.

2. In a dentrem'oving tool, a substantially U- shaped frame includingrst and second arms, a rst guide vat the free end of the rst arm, asecond guide at the free end of the second arm, a hammer mounted forreciprocation in the second guide, a removable closure plugin the outerend of the rst guide and having a bore in its inner sponding arms inFig. 1, diagonal braces 24 connecting the intermediate portionlb of theframe 3b with the arms Ib and 2b, in the interest of increased strengthin the frame 3b.

In any of its forms, `the device forming the subject matter of thisapplication will be found thoroughly effective for the purposehereinbefore explained.

The constituent material of the tool may be selected as desired, and itwill bev understood that hardening, or hard metal, may be resorted towherever necessary or desirable. The function of the projection I 9 onthe hammer I'I. coop# erating with the slot 20, is to prevent the hammerfrom becoming detached by dropping out of end, an annular stop in thefirst guide, an indicator pin mounted for reciprocation in the bore andin the stop, the pin being provided with an abutment, a compressionspring surrounding a portion of the pin, one end of the spring engagingthe inner end of the plug', the opposite end of the spring engaging theabutment, the length of the pin from its cuter'end to the abutment beingsuch that the abutment will engage the stop before the outer end of thepin is withdrawn from the bore, and the inner ends of the pin and of thehammer being disposed in axial alinement.
